Quad9

This is by far my favourite DNS at the moment, its power blocking trackers and ads is almost one to one to AdGuard & allows me to go to my Country's ISR webpage which AdGuard blocks. probably because the ISR's webpage has poor or the lack of certificates but Quad9 does the job amazingly without those compromises.

El servicio bloquea sitios maliciosos, pues reviso listas que incluyo en pi-hole y Quad9 ya las tiene como sitio "sin respuesta" o sea no las resuelve y por ende no se puede establecer una conexión (por parte de los virus). Lo recomiendo.

"Quad9 blocks only sites that present a danger to the end user, their equipment, or the network. Quad9 does not block content, and the agreements with threat intelligence providers stipulate that the criteria for blocking be exclusively security-related and not based on other categories."

I was really liking my NextDNS, but it seemed to conflict w/PortMaster, so I decided to choose between their options and choose Quad9. Quad9 is Swiss, and the Swiss privacy laws are great.

Lately I discovered than Quad9 do a better business to protect you than paid service like Cisco Umbrella and DNSFilter (ref: https://www.youtube.com/watch?v=imlFubYv8YY) It is also almost as fast than Google DNS which do nothing to protect you and probably spy on your query.

was a bit faster than google though , and the no logs beats google , but not fast enough for me in the uk ..
